Definitions

  • the present invention relates to a locking device for two elements which are in mutual screwing relationship.
  • the present invention also relates to a pipe fitting equipped with such a device.
  • the function of the locking device is to prevent the unwanted unscrewing of the two elements with respect to each other, particularly in applications where the two elements are subjected to vibrations or vibrations during operation.
  • the invention is more particularly but not limited to standardized couplings comprising a nipple at the end of one of the pipes, intended to be pressed into a flare of the end of the other pipe, under the clamping action. a captive nut of one of the pipes and engaging with a thread formed on the other pipe.
  • the US 6,293,595 B1 discloses such a locking device capable of simultaneously engaging, by axial movement under the pressure of a spring, with the hexagon-shaped configuration of the nut and with a stop member integral with the male end of the pipe. To be able to separate the two pipe ends, it is necessary to push the coupling member against the return spring into the position where it is disengaged from the hexagonal configuration provided on the nut and / or the stop member secured to the male end of the pipe.
  • This known device has the considerable advantage of being adaptable to a standard pipe fitting without other modifications that the simple attachment of a carrier body on the male end of the fitting.
  • the object of the present invention is to improve the locking device known in terms of ease of use.
  • a reversible ratchet system is very effective in preventing unscrewing under the effect of vibrations.
  • the ratchet releases the two elements relative to each other only when a resistance resilient has been overcome over a sufficient angular distance to reach the point of crossing the top of a ratchet tooth.
  • vibratory excitations in one direction or the other are too short for this process of crossing the top of the tooth is possible.
  • the process can certainly begin, but it is followed by a springback to the most stable snap situation.
  • the locking device according to the invention can be designed fully compatible with standard pipe fittings without these requiring other modifications than the attachment of the body of the device on the second element.
  • it is the nut which constitutes the second element. It is indeed easier to make a special nut, especially in the case of retrofitting.
  • the two end pieces can be completely disengaged when they are in the uncoupled state, simply by sliding the nut far enough back along the pipe carrying it, and the locking device. locking does not create any discomfort to move a pipe laterally relative to the other.
  • the pipe fitting comprising a pipe end fitted with a male thread and a nut screwed onto the male thread and rotatably mounted on another pipe end, is characterized in that it comprises in addition a locking device according to the first aspect, for selectively locking the relative rotation of the two elements constituted by the nut and the endpiece provided with a male thread.
  • the locking device 1 is adaptable to a pipe coupling comprising a male end 2 -or nipple-, integral with one of the pipes to be connected, and a female end 3, secured to the other of pipes to be connected, as well as a nut 4.
  • the ends 2 and 3 comprise at their free end a male, ovoid-shaped sealing conformation 6 and respectively a female frustoconical conformation 7, designed to bear tightly against each other.
  • the nipple 2 comprises a male thread 8 and then a collar 9 bearing on its periphery a conformation of such that a conformation 11 is distant or disjoint from the thread 8 of the element 2 in the sense that this conformation 11 that will be used for the locking is not constituted by an alteration of the thread such as a flat or a groove removing part of the threads.
  • the nut 4 has at its rear end, opposite to the tip 2, an inner collar 12 and an outer conformation of turning engagement 13 such as a six-sided conformation.
  • the inner collar 12 engages behind a shoulder 14 of the tip 3.
  • the shoulder 14 is turned away from the tip 2 to hold the nut 4 prisoner and to receive from the nut 4 a force urging the sealing conformation 7 to seal against the sealing conformation 6 of the nozzle 2.
  • the nut 4 is extended forward by a tube 32 which comprises from its front end facing the end piece 2 a female thread 16 capable of cooperating with the thread 8 of the end piece 2 to produce the clamping force supra.
  • the locking device 1 comprises a support body 18 - or cup - having at its rear end a sleeve 19 which is fitted around the six-sided conformation 13 of the nut 4.
  • the sleeve 19 comprises an inner surface 21 of prismatic shape with hexagonal contour which allows the sleeve 19 to be fitted substantially without play on the six-sided conformation 13 (see also figure 2 ).
  • the nut 4 and the body 18 are integral in rotation.
  • the sleeve 19 is equipped with retaining means for axially securing the sleeve 19 and thus the body 18 with the nut 4.
  • the retaining means further comprise, in the version shown at the top of the Figures 1 and 2 , latching lugs 24 cut in the wall of the sleeve 19 by substantially axial slots 26 opening in the rear edge of the sleeve 19.
  • the latching lugs 24 are terminated by latching lugs 27 which engage when the assembly is performed on the rear face 28 of the nut 4, adjacent to the rear annular edge of the six-sided conformation 13.
  • the retaining means comprise crimping tongues 29 which are initially in the extension of at least some of the faces of the inner surface 21 of the sleeve 19 ( figure 2 ). Once the assembly is completed, the tabs 29 are plastically folded against the rear surface 28 of the nut 4, as shown at the bottom of FIG. figure 1 .
  • the sleeve 19 has on its outer surface its own six-sided conformation 25 intended to replace the six-sided conformation 13 of the nut to allow the rotating nut to be operated using a tool such as a key (not shown) when the device 1 is in place.
  • the sleeve 19 is connected rigidly and in one piece to the rear end of a skirt 31 of generally cylindrical shape which extends around the tube 32 forming an annular chamber 34 between the skirt 31 and the tube 32.
  • a helical compression spring 36 having the same axis 37 as the pipe, a stop member 38 of annular shape around the axis 37 and having pads 39 mounted sliding in axial grooves 41 of the inner wall of the skirt 31, and finally a coupling member 42 having on its outer periphery a boss 43 which prevents the coupling member 42 from disengaging itself from the skirt 31 while abutting against a flange terminal 44 of the skirt 31, formed by plastic deformation, protruding radially towards the axis 37.
  • the coupling member 42 protrudes outside the skirt 31 beyond the end flange 44 and has in its front part, which protrudes from the skirt 31 at least when the spring 36 is in the relatively uncompressed state, a female hexagonal recess 46 of a caliber corresponding to that of the male six-sided conformation 11 of the first element 2.
  • the axial width of this impression is much smaller than that of the six-sided conformation 11 and is delimited at its rear end by abutments 47 intended to bear against a shoulder 48 adjacent to the six-sided conformation. This support limits the axial grip of the impression 46 on the conformation 11.
  • the axial dimensioning of the assembly is such that when the two endpieces 2, 3 are in new condition ( figure 1 ) are pressed axially tight against each other by the tightening exerted by the nut 4, the coupling member 42 is engaged with the six-sided conformation 11, the stops 47 are pressed against the shoulder 48 while the abutment 43 is almost pressed against the flange 44.
  • the pipe fittings of the generic type targeted by the invention tend to wear by radial contraction of the male part 6, and widening or widening of the frustoconical portion 7. This has the consequence of increasing the stroke of the nut 4 along the first member 2 which is necessary for the desirable axial clamping is achieved.
  • This is taken into account according to the invention by a sufficient compression stroke of the spring 36, and initial axial mobility distances sufficient d ( figure 1 ) between the coupling member 42 and the free end of the nut 4, and D between the rear end of the pads 39 and the bottom of the chamber 24.
  • the stop member 31 and the coupling member 42 have on their annular edges turned towards one another axially directed teeth 49, 51 and having a symmetrical profile. That is to say that with respect to a circumferential direction, the teeth, which are of triangular configuration, each have a front face and a rear face which have same oblique slope.
  • the teeth 49 of the stop member 31 and the teeth 51 of the coupling member 42 have complementary profiles of so that they can interpenetrate as represented at the top of the figure 1 and to Figures 4 and 5 . On the other hand, at the bottom of figure 1 , the teeth are pointed against points.
  • the device 1 is fitted onto the nut 4 from the front end of the nut 4 until the collar 22 abuts against the shoulder 23.
  • the tabs 24 are urged radially outwardly to cross the shoulder 23 and then redetend elastically inwards when the beaks 27 can snap behind the face 28 of the nut 4.
  • the fitting takes place without resistance until the collar 22 abuts against the shoulder 23.
  • the crimping tongues 29 are folded radially. inward as depicted at the bottom of the figure 1 . It is remarkable that the device 1 forms a single unit entirely amounting to only one of the elements to lock mutually, without requiring any development on the other element.
  • the nut 4 is screwed around the thread 8 of the nozzle 2 by using a wrench which is in engagement with the hexagon-shaped conformation 11 of the nozzle 2 and another wrench which is taken with the six-sided conformation 25 of the device 1.
  • the stop member 42 abuts against the flange 44 under the action of the compression spring 36.
  • the body coupling 42 abuts against the shoulder 48 of the nozzle 2, the spring 36 begins to compress then, as the member 42 is rotated by the interpenetration of the teeth 49 and 51, its fingerprint 46 ends up coinciding with the conformation 11 of the endpiece 2 and the spring 36 causes, while redetching itself, the interlocking of the impression 46 on the conformation 11.
  • the coupling member 42 is prevented from rotating with the nut 11 and the teeth 49 and 51 click on each other with each time a brief compression of the spring 36 when the teeth 49 and 51 are found spikes against points as illustrated at the bottom of the figure 1 .
  • the body d stop 38 prevented from rotating relative to the body 18 thanks to the pads 39 engaged in the grooves 41, and the coupling member 42 prevented from rotating relative to the stop member 38 due to the interpenetration of the teeth 49 and 51.
  • the device could also be associated with the male end 2 and make it cooperate, for locking, with the six-sided conformation 13 of the nut. This solution is less preferred because it does not allow to disengage the elements of the connection once loosening.
  • the teeth 49 and 51 have a different resistance to screwing and unscrewing, they can be made asymmetrical but they must always have a sufficiently low slope to be able to cross each other under the simple action of a couple of rotation exerted on the locking device 1 relative to the other element which is not equipped with the device.
